Search for "loping" on this forum and see if you like how that sounds as well before you put a 2 bros pipe on there. I guarantee you it will make your bike run like shit, unless you get it custom tuned which would be a colossal waste of money with that exhaust.

I rode all season with it and have no complaints other than the magnesium bolts which strip easy. I used the silencer in it because they started putting out sound snares around the city and issuing tickets, but I took it out after a week because I didn't like it. I'll be installing a PC3 on it now that there is snow covering the roads here, I found a map on their website for a two bros slip-on, I just need a PC to download it.

Lovely. I have two bros pipe on mine and i love the sound. Sometimes i use the bike for long runs and it was too loud and got myself sound suppresor.
If you have somebody to record you with a nice camera, make a video when you accelerate in first gear, from standing to redline on rpm, it sounds like a Formula 1 car taking off.

I agree, it does sound like an F1 car. There is snow covering the roads here now but I will take a clip of it through first gear in the spring.

2bros only makes sound, but NOT MUCH POWER is gained. a real performance exhaust like Akrapovic, Sato, Arata, Ladybird makes REAL performance gains while still being loud with a beautiful sound. facts are facts. but to each his own, i wont hate on anyone that puts a two bros pipe on; it sounds nice and loud, but i rather make more power than noise. and my arata is loud as hell especially at WOT
